A while back I found (somewhere on the internet) a set of instructions for replacement of the 2405 diaphragm. I believe it was a JBL document (can’t swear to it), however, I have been unable to locate it on the JBL site. At the time I found it I printed out a hard copy of the instructions and filed it away, however, I’m at a loss to find that also. Now that I’m ready to replace my non-JBL 2405 diaphragms with original JBL’s I would like to find them again. I read the instructions at the time I downloaded them and even opened up the 2405’s and feel pretty confident but a reread can’t hurt. I’ve replaced several Altec diaphragms and the process as I remember it is about the same but it would be nice to have the instructions as a safety net and be sure I didn’t forget/overlook something. If anyone knows the link or can provide any help I would appreciate it. Thanks.
